Elucidating the Mechanism Governing Particle Alignment and Movement by DEP

G. Zhang [1], Y. Zhao [1], J. Brcka [2], J. Faguet [2],
[1] Clemson University, Clemson, SC, USA
[2] Tokyo Electron U.S. Holdings, Inc., Austin, TX, USA

We have simulated alignment and movement of multiple particles under Dielectrophoresis (DEP) using the Particle Tracing Module in COMSOL Multiphysics® software with particle-particle interaction taken into consideration. We are able to do efficient modeling for both 2D and 3D cases. With ... Mehr lesen

Preliminary Study of Particle Trajectory and Secondary Flow in Bend Configurations to Reduce Erosion

To the best of our knowledge, only few researchers have made attempts to minimize the erosion in bends by modifying the bend configuration in order to alter the particle-laden flow pattern to reduce the erosion. In this work, we revisited those previously proposed bend configurations to ... Mehr lesen

Particle Focusing Optimization and Stress Analysis of a Magnetic Horn

[2]Swiss Federal Institute of Technology, ETH, Zurich, Switzerland

A neutrino oscillation experiment aims to the observation of the transformation of a neutrino of a given flavour into a neutrino of a different flavour. A beam of neutrinos is produced through the decay of charged pions which in turn are produced in the collision of high energy ... Mehr lesen

Simulation of Microfabricated Linear Ion Trap

[1]Aalto University, Department of Micro- and Nanosciences, Espoo, Finland

We present a simplified 3D model that simulates the operation of a linear microscale integrated ion trap. It employs a set of metalized electrodes, which are formed on top of an insulator layer on silicon substrate. The confinement in all three dimensions is provided by the application ... Mehr lesen

Molecular Gas Flow in a Fish Trap Nozzle – Challenge to the Second Law of Thermodynamics

R. Eisenschmid[1]
[1]OPTIMA pharma GmbH, Schwäbisch Hall, Germany

During examination of molecular gas flow in freeze dryers in near-vacuum properties, an idea came up to model a molecular fish trap nozzle. An appropriate shape of this fish trap nozzle allows to separate free flowing molecules into 2 chambers, and obtain a pressure gain in a isothermal ... Mehr lesen

3D-Modeling of Magnetophoretic Separation of Superparamagnetic Dispersions Using COMSOL Multiphysics® Particle Tracing Module

D. Kleinehanding[1], L. Teich[1], C. Schröder[1]
[1]Department of Engineering Sciences and Mathematics, Computational Materials Science & Engineering (CMSE), University of Applied Sciences Bielefeld, Bielefeld, Germany

Magnetophoresis is a process of great interest for novel applications based on magnetic nanoparticles and colloids. Environmental applications like wastewater treatments and pollutant removal, biomedical applications like protein isolation, drug delivery, magnetic hyperthermia for cancer ... Mehr lesen

Behavior Models of Virtual Impactors

R. Haft[1]
[1]Lawrence Berkeley National Laboratory, Hayward, CA, USA

A pocket-size portable particle size detector for diesel and cigarette smoke aerosols is being designed using particle size and composition methods. Aerodynamics, fluid properties, material composition and aerosol composition are taken into account. Testing methods for the design include ... Mehr lesen

A Computational Study of the Reynolds Piped flow Experiment

Sanidhya Painuli[1], Jayasankar Variyar[1]
[1]Vellore Institute Of Technology, School of Mechanical and Building Sciences, Vandalur Kelambakkam Road, Chennai, India

The study of interaction of fluid with matter assumes great significance for most engineering applications. The flow can be either turbulent or laminar, and different types of interactions arise out of these flow. In the introductory undergraduate course of fluid mechanics, a typical ... Mehr lesen
